treadmillG'day, members!
The game is simple (but not as simple as it looks!) Essentially, all you have to do is try to figure out what the image is trying to 'spell out' i.e. What 'word' does the image presented represent?
EDIT: Guys, sorry - I stupidly forgot to turn the auto-spoilers on in this thread. Please don't scroll down until you've tried to solve the puzzle yourself or you may see another member's answer.
